PNG to WebP Converter
Turn PNG files into WebP in seconds. Everything happens on your device: nothing is uploaded, and there's no limit.
Your images are processed in this browser tab and never uploaded.
Why convert PNG to WebP?
PNG files can be large, especially for photos.
WebP files are much smaller, so websites load faster and use less storage.
What to expect
- WebP is lossy, so the file gets much smaller. At the default quality (90%) the difference is very hard to see; you can change it before converting.
Making website images smaller with WebP
WebP is the format page-speed tools like Google PageSpeed Insights recommend under “Serve images in next-gen formats”. A PNG photo typically drops by 60 to 80% as a lossy WebP, and graphics with transparency keep their transparent background.
Every current browser shows WebP, including Safari since 2020 (macOS Big Sur and iOS 14). WordPress has accepted WebP uploads since version 5.8.
Tips
- Logos and icons with sharp edges: keep the quality at 90% or more so edges stay crisp.
- Keep the original PNG files. Some print services and older desktop apps still don't open WebP.
- For the smallest possible files, try AVIF as well and compare the two sizes.

About the formats
PNG (Portable Network Graphics, 1996) is a lossless format that keeps every pixel exactly. It supports full transparency, which makes it the standard for logos, screenshots and graphics with sharp edges.
WebP (WebP, 2010) is Google's modern web format. It makes files roughly 25–35% smaller than JPG or PNG at the same visual quality and supports both transparency and animation.
Frequently asked questions
How do I convert PNG to WebP?
Drop your PNG files into the box above (or tap Select files), check the options, then press Convert. Each WebP downloads on its own, or you can download them all as one ZIP file.
Are my files uploaded anywhere?
No. The conversion runs entirely in your browser on your own device. Your PNG files are never sent to a server, so they stay private, and it works even on a slow connection once the page has loaded.
Is there a limit on how many PNG files I can convert?
No. Convert as many as you like, for free, without signing up. Very large batches are processed one after another so your browser stays responsive.
Will I lose quality converting to WebP?
WebP uses lossy compression, but at the default 90% quality the difference is practically invisible. Move the Quality slider up for the highest fidelity or down for smaller files.
Does WebP keep transparency?
Yes. Transparent and semi-transparent areas of the PNG are kept in the WebP.
Does it work on iPhone and Android?
Yes. It works in Safari, Chrome, Firefox and Edge on phones, tablets and computers. Nothing to install.
